UTIs and Urine Bacteria in Aging:
How to get the right diagnosis & avoid unneeded antibiotics

Q: An older friend, who is in her 90s, has been having bacteria in her urine, but no symptoms. Despite treatment with antibiotics, she was still having bacteria in the urine, so the doctor recommended chronic antibiotics and a referral to urology.

What can be done when an elderly woman has bacteria in her urine but no symptoms? Can a urology consultation help?

A: This is a great question. People often think that your friend is having a “recurring urinary tract infection (UTI)” or even a chronic UTI. But actually, you are describing something called asymptomatic bacteriuria, which means having urine bacteria without symptoms.

Every older person and family caregiver should know about asymptomatic bacteriuria. Here’s why:

It’s very common in older adults. This condition is found in an estimated 20% of women aged 80 or older, and also affects older men. The older the person, the more common it is. Asymptomatic bacteriuria is even more common in nursing homes, where it’s estimated to affect 30-50% of residents.

It’s often confused with a urinary tract infection (UTI). This can lead to unnecessary — and potentially harmful — treatment with antibiotics.

It usually does NOT need to be treated with antibiotics. As I’ll explain below, research shows that people don’t live better or longer when asymptomatic bacteriuria is treated. In fact, such treatment can be harmful: one study found that treatment increased the risk of future (real) UTIs, and increased the risk of infection with antibiotic-resistant bacteria.

Q&A: How to Diagnose & Treat Mild Cognitive Impairment?

by Leslie Kernisan, MD MPH

Q: I realize that I sometimes have difficulty connecting a name and a face. I presume that this is mild cognitive impairment.

On researching the topic online, I find a variety of suggestions for alleviating it. These include supplements (lipoic acid, vitamin E, omega 3s, curcumin), food choices (fish, vegetables, black and green teas), aerobic exercise, yoga, and meditation.

Do these actually help with mild cognitive impairment? What’s been proven to work?

A: It’s common for older adults to feel they’re having trouble with certain memory or thinking tasks as they get older.

I can’t say whether it’s mild cognitive impairment (MCI) in your particular case. But we can review what is known about stopping or slowing cognitive changes in people diagnosed with MCI.

First, let’s start by reviewing what MCI is, and how it’s diagnosed. Then I’ll share some information on the approaches you are asking about, as well as other approaches for treating MCI.

Understanding Laboratory Tests:
10 Commonly Used Blood Tests for Older Adults

by Leslie Kernisan, MD MPH

In this article, I’ll address a real mainstay of modern medicine: laboratory tests that require drawing blood.

This is sometimes referred to as “checking labs,” “doing bloodwork,” or even “checking blood.”

Most older adults have been through this. For instance, it’s pretty much impossible to be hospitalized without having bloodwork done, and it’s part of most emergency room care. Such testing is also often done as part of an annual exam, or “complete physical.”

Last but not least, blood testing is usually — although not always — very helpful when it comes to evaluating many common complaints that affect aging adults.

Fatigued and experiencing low energy? We should perhaps check for anemia and thyroid problems, among other things.

Confused and delirious? Bloodwork can help us check on an older person’s electrolytes (they can be thrown off by a medication side-effect, as well as by other causes). Blood tests can also provide us with information related to infection, kidney function, and much more.

10 Useful Types of Medical Information to Bring to a New Doctor

by Leslie Kernisan, MD MPH

Personal health information to bring to a new doctor

Here’s a situation that comes up for many people: you move in later life.

Or maybe it’s your older mother — or father, or other older relative — who’s moving to a new town, perhaps to be closer to you, or otherwise be somewhere more conducive to aging in place.

Such a move means that you’ll need to establish care with a new primary care provider.

For most older adults, establishing a good working relationship with a new health provider is a challenge. If nothing else, it can take some time to feel that each party knows and understands the other.

But it’s also in many cases a terrific opportunity to review a person’s health and healthcare. Provided, of course, that everyone involved makes an effort, and has good information to work with.

In this post, I’ll share my list of the most useful medical records and health information that you should bring to that first visit with the new primary care provider.

Do you have to bring this information? Of course not. In my own experience, most people bring nothing more than a medication list, if that. And they leave it to the new doctors to request health information from the previous doctors, which often arrives well after that first new patient visit.

But this is a problem, because it makes it quite difficult for that first visit to be truly useful.

Sure, the doctor can interview you, and do a physical exam. Yet for many older adults, that interview and exam is often much more productive if a doctor can combine it with a review of the most useful health information.

I myself used to see a fair number of new older patients, when I was a primary care geriatrician at the Over 60 Health Center. Those first visits often felt like fumbling around in a dark room, feeling the walls and furniture and trying to get a sense of the overall layout.

But occasionally, a new patient would come with useful health information in hand. This generally made a big difference in how quickly we could ensure that our new patient was getting the right medical care from us, and from other involved doctors.

So if you want to have the best start possible with a new doctor — or help your aging parent do so — you’ll need to do a little advance preparation. This often requires some time and energy. But it will pay off, by ensuring that the new doctor has the information he or she needs, to provide you with good healthcare.

Also, if you are in that season of life where you’re starting to be more involved with your aging parent’s health (or think perhaps you should be), this is a great opportunity to learn more about your parent’s health.

10 Useful Types of Medical Information to Bring to a New Primary Care Provider

Here’s my list of what I ask patients and families to bring to me, in order to make that new patient visit most useful.

5 Top Causes of Sleep Problems in Aging, & Proven Ways to Treat Insomnia

by Leslie Kernisan, MD MPH

What should you do if an older person complains of not sleeping well at night?

Experts do believe that “normal aging” brings on some changes to sleep. (See this post for more on how sleep changes with aging.) Basically, older adults tend to get sleepy earlier in the evening, and tend to sleep less deeply than when they were younger.

So it’s probably not realistic to expect that as you get older, you’ll sleep as long or as soundly as when you were younger.

That said, although aging by itself does change sleep, it’s also quite common for older adults to develop health problems that can cause sleep disturbances. So when your older relatives say they aren’t sleeping well, you’ll want to help them check for these. Figuring out what’s going on is always the first step in being able to improve things.

And remember, getting enough good quality sleep helps maintain brain health, physical health, and mood.

In this article, I’ll cover the top causes of sleep problems in older adults. I’ll also tell you about what approaches have been proven to work, to help treat insomnia and sleep problems in older adults.

Last but not least, if you (or your older relative) have experienced the very common combination of waking up to pee at night and difficulty sleeping, I highly recommend listening to this podcast episode, which features a geriatrician who is an expert on this: 092- Interview: Addressing Nighttime Urination & Insomnia in Aging.

Cognitive Impairment in Aging: 10 Common Causes & 10 Things the Doctor Should Check

by Leslie Kernisan, MD MPH

Have you been worried about an older person’s memory or thinking abilities?

Maybe your parent has seemed more confused recently. Or you may have noticed that your aging spouse is repeating herself, or struggling to do things that didn’t use to pose much of a problem.

Or you may have noticed false accusations, or irrational worries getting out of control.

These are very common concerns, and they often lead to questions such as:

Is this normal aging or something more significant?
What is wrong?
Could this be Alzheimer’s? Or some other form of dementia?
Can these memory problems be treated or reversed?
What should we do about this??

The answer to the last question is this: if you are worried about memory or thinking, then you should seek out some kind of medical evaluation.

That’s because when families worry about an older person’s cognitive abilities, there often are some underlying health issues affecting the mind’s function.

Those need to be detected, and treated if at all possible. So, you’ll need to request help from a health professional, and in this article, I’ll explain what that initial help should consist of. This way you’ll know what to expect, and what the doctor might ask you about.

Technically, these kinds of problems are called “cognitive impairment.” This is a broad term that means some kind of problem or difficulty with one’s memory, thinking, concentration, and other functions of the conscious brain, beyond what might be expected due to normal “cognitive aging.”

(For more on “cognitive aging” and what types of changes are considered normal aging, see this article: 6 Ways that Memory & Thinking Change with Normal Aging, & What to Do About This.)

Cognitive impairment — which is also called “cognitive decline” — can come on suddenly or gradually, and can be temporary or more permanent. It may or may not keep getting slowly worse; it all depends on the underlying cause or causes.

In this article, I’ll share with you the more common causes of cognitive impairment in older adults.

I’ll then share a list of 10 things that should generally be done, during a preliminary medical evaluation for cognitive decline in an older adult.

Choosing & Using a Home Blood Pressure Monitor, & What to Ask the Doctor

by Leslie Kernisan, MD MPH

In another article, I’ve explained the key reasons that I recommend older adults and their caregivers have a blood pressure (BP) monitor at home.

To very briefly recap:

Many of the problems of older adults (including falls) can be related to blood pressure.
Home blood pressure measurements can help:
- evaluate for drops in blood pressure with standing (a common cause of dizziness in elders)
- check for serious illness, since these often (but not always) cause the blood pressure and pulse to be very different from usual
- follow-up on blood pressure after a change in medication, which can help doctors and families figure out the best medication dosing for an older person much faster. This is safer for seniors.

In this post, I’ll share some tips on choosing and using a home BP monitor.

And don’t worry: I won’t tell you that you have to plan on checking every day for the rest of your lives. Although there are times when it’s great to check daily — like the week after a change in medication — the most important thing is to have a good BP monitor at home and know how to use it at least occasionally.

Providing Elder Care: Covering the Cost of Home Care, Assisted Living & Other Options

by Leslie Kernisan, MD MPH

One of the most common questions I get asked is “How can I get care for my aging parent and how much will it cost?”

The answer generally depends on these factors:

What kind of elder care does the older person need or want?
What are the available options for providing the needed elder care?
How much do the different options cost?
What are the options for paying for the desired type of elder care?

These are important questions to consider. If your aging parent seems to need help, it’s imperative to find out what are your options for providing the needed support. And finances do often determine how a family proceeds with arranging elder care.

And even if your aging parent doesn’t need help now, they very well might in the future. So it’s also reasonable to plan ahead, and consider how elder care might be provided, if/when it becomes needed in the future.

Now, the truth is that most older adults don’t need much assistance from others. But research shows about 70% of older adults do end up needing some form of “senior care,” for a time ranging from a few months to several years.

So in this article, I’ll share the key things to know, about options for elder care and how to pay for it. Specifically, I’ll cover: [Read more…]

9 Types of Issues to Address When Helping Older Parents

by Leslie Kernisan, MD MPH

Most older adults don’t need much help from others.

In fact, many of them are quite busy assisting others and otherwise contributing to their families, communities, and/or workplaces.

But of course, many older people eventually do need some help from others, especially if they live into their 80s, 90s, or beyond. After all, only a minority of people transition from being fully independent to deceased, with no intervening period of needing assistance.

(Wondering how to get an older person to accept help? That’s covered here: 6 Steps to Take When Aging Parents Need Help – Even if They’re Resisting.)

When an older person does start to need help, it tends to be close family members — assuming the person has family — that step in: spouses, adult children, siblings, nephews or nieces, grandchildren, and so forth. In fact, family members are by far the number one source of “long-term care supports and services” for older adults.

Sometimes providing this eldercare support can be fairly straightforward: a little help with transportation, or arranging for some assistance with shopping or household chores.

But in other cases, family members find themselves having to take on quite a lot. This is often due to health issues affecting the older person’s ability to remain independent and manage various aspects of life.

Some situations that commonly bring this on include:
